Hello Stoo, and thank you for your in depth research and analysis into this case!
I was doing some digging today, looking for some of the reports that were assembled and sourced from to create the overall report excerpted in the
CUFON online report.
I realized last night while thinking about that line of research, that to the layman all of this 'report' terminology can perhaps be confusing. To
clarify, I'll try to lay it out as I understand the process:
CUFON Report - This is an Adobe .pdf version of an assembled report titled, "The History of the 4th AA Command, Western Defense Command, Jan 9 1942
to July 1 1945".
As I understand it, the above cited report was declassified as a result of a FOIA (Freedom of Information Act) Request by CUFON, fulfilled by the
United States Government.
This report is actually a 'point-by-point' review of events during the stated timeframe, that drew from myriad initial reports, citing each
individual report directly through the use of footnotes.
This is a good and bad thing, for a researcher. On the good side, it means that nearly every statement made in the overall report (The History of the
4th AA Command...) has a full report from which that statement was drawn, in existence somewhere. There is further supporting data contained in these
initial reports, that will certainly help us to clarify the statements made in the overall report.
On the bad side, this means that each of these cited sources are now on the researchers 'target' list.

We, as responsible investigators, should
attempt to assemble as many of these supporting reports as possible, and link to them here in the thread. If anyone comes across such a report,
please let us know!
In researching the initial report I mentioned earlier on this page (regarding the 'dirigible' statement...) we're looking for this document:
App B, Doc 28, incl #1, Page 6
Interestingly enough, when I began to search for this document, new information began to come forth...
For example, in the 'End Notes for Chapter 3', linked here:
www.history.army.mil...
We find the following cited source:
"46 Antiaircraft Artillery Def Project, ETO, 1942, 10 Jan 42, submitted to the General Staff by Ltr, GHQ to TAG, 4 Feb 42, AG 660.2 AA (1-1-40), sec.
I; various papers, WPD 4627-5, especially Memo, CofCA for WPD, 21 Feb 42."
This source (#46 down the page...) clearly seems to contain reference data from the Military pertaining to the Battle of Los Angeles, if the reference
indicator at the end of the source is accurate...
Also of note from this page are:
"48 Terrett, The Emergency, ch. V, and app pp. 318-25, in which the Army radars of World War II are identified and described ."
and:
"52 Memo, Col Sherrill for ACofS WPD, and atchd tab A, 8 Jan 42, WPD 4187-25; Incl to Signal Corps Memo, 14 Jul 42, title: Distribution of Ground
Radar Sets in Cont U.S., cited in Thompson et al., The Test, p. 290."
and:
"53 History of the Western Defense Command, vol. III, ch. 10, contains a map of the overwater coverage of the twenty-five radar installations
maintained along the west coast in 1943."
and:
"76 Stimson Diary, entry of 18 Dec 41; Ltr, SW to Chairman, Senate Comm on Military Affairs, 30 Mar 42, OCS 15491-133; Memo, Chief, Admin Services,
SOS, for G-1, 30 May 42, AG 383 (5-30-42) (2) ; WD Relationships With OCD, p. 12."
and:
"104 See, for examples, Memo, CofS for ASW John J. McCloy, 24 Feb 42, OCS 15450-15; Ltr, CofS to Hon. Warren R. Austin, U.S. Senate, 28 Feb 42, WDCSA
381 Nat Def (2-28-42)."
All of the above cited references may contain relevant supporting data, pertaining directly to this case...
I also found this today:
ibiblio.org...
Wherein I found this description:
"Radar, though never completely reliable, normally permitted the operation of Army guns and searchlights at their maximum range instead of at a
visual range determined by weather conditions.17"
The 17 at the end of that sentence was a source citation reading:
"17. Hist of EDC, p. 29; for types of harbor defense radar, see Dulany Terrett, The Signal Corps: The Emergency, UNITED STATES ARMY IN WORLD WAR II
(Washington, 1956) (hereafter cited as Terrett, The Emergency), app. "
This source might also prove a valuable source of information on Radar/Gunner operations protocol.
Well crew, unfortunately, that's all the time I have for today in the research dept. I'll certainly be tracking these sources down in my free time,
and I hope that any of you out there with a keen eye for research will help to uncover these reports for further examination here at ATS!
More to come as new information emerges...
